云数据中心异地迁移的设计与实现

Design and implementation of remote migration of cloud data center

目前,在云计算的浪潮下,云的安全性也显得越来越重要。当某地出现了严重的灾害,导致云服务不能正常运转时,我们需要将此地的服务数据迁移到另一个地方。为此云上的应用及服务提供一定的安全保障是现在急需解决的问题。当某服务发生故障,我们便需要把该服务迁移走,避免占用数据中心的资源。如何使用VXLAN技术在云环境下迁移虚拟机是技术的核心问题。

At present,in the wave of cloud computing,cloud security is becoming more and more important.When a serious disaster occurs in a certain place,leading to cloud services can not work normally,we need to migrate the service data of this place to another place.Therefore,it is an urgent problem to provide a certain security guarantee for the applications and services on the cloud.When a service fails,we need to migrate the service to avoid occupying the resources of the data center.How to use vxlan technology to migrate virtual machine in cloud environment is the core problem of the technology.
